| Episode narrativeepisode_narrative | Thunderstorms developed early this Wednesday afternoon and evening, and predominantly produced tornadoes and flash flooding. Five tornadoes occurred over Jewell County. With no cap in place, scattered thunderstorms began developing as early as the noon hour over north central Kansas. Most storms rapidly became supercellular. These supercells began producing severe weather by 330 p.m. CDT. It was about this time that a short line formed from the Jewell-Smith County line south into Osborne County. Supercells were embedded within this line and several discrete supercells developed ahead of it over Mitchell and Jewell counties. Eventually, an MCS developed. The leading edge of the cold pool becoming stationary, with new storms repeatedly developing over north central Kansas and further downstream into southeastern Nebraska. Cell training produced a swath of 4-8 inches of rain over portions of Jewell County. The highest amount reported was 7.92 inches near Webber. ||A complex low pressure system extended from the Canadian Prairies into the western United States. These storms developed in the warm sector, far away from any discernible surface boundaries. However, an axis of confluence was present over north central Kansas. A deep upper-level trough was over the western U.S., with a ridge over the East. In the southwest flow between these features, a shortwave trough was lifting through the Central Plains. These storms formed in the southeast quadrant of the associated vorticity maximum. Around the time thunderstorms developed, temperatures were in the lower 70s with dewpoints in the lower 60s, resulting in low cloud bases. Even at mid-afternoon, cloud bases were only 2000-2500 ft. The surface conditions and mid-level lapse rates of 7 degrees C/km resulted in SBCAPE was around 1500 J/kg. Deep layer shear was only 25-30 knots. However, low-level wind fields were strong with 40-45 knots at 850 mb. This resulted in large hodographs with 0-1 km SRH values of 200-250 m2/s2, and 0-3 km SRH of 250-300 m2/s2. Combined with low cloud bases, this created a favorable environment for supercells and tornadoes. |
